It's very surprising to me that this kind of cost monitoring is treated
as an afterthought, especially since one of the main jobs of the X.Org
board is to keep spending under control and transparent.

Also from all the conversations it's still unclear to me if the google
hosting costs are already over the sponsored credits (so is burning a
hole into X.org bank account right now) or if this is only going to
happen at a later point in time.

Even with CI disabled it seems that the board estimates a cost of 30k
annually for the plain gitlab hosting. Is this covered by the credits
sponsored by google? If not, why wasn't there a board voting on this
spending? All other spending seem to require pre-approval by the board.
Why wasn't gitlab hosting cost discussed much earlier in the public
board meetings, especially if it's going to be such an big chunk of the
overall spending of the X.Org foundation?
